Choosing car accessories without costly mistakes: a practical guide to safe, comfortable driving

Car accessories can make your car safer, more comfortable or easier to maintain. However, not every product is right for every driver. A low price tells you little about compatibility, fitting or everyday use. If you want to buy car accessories, it’s worth checking what you need them for and reviewing the technical specifications first.

Common pitfalls when choosing car accessories

1. “Universal” doesn’t always mean a perfect fit

A product described as universal car accessories may suit many vehicles, but always check the connections and dimensions. For example, a CarPlay screen that uses a 12V socket won’t necessarily fit neatly on every dashboard. Check that it supports your smartphone, too: some models require iOS 10, iOS 12 or Android 11 and above.

2. Marketing claims can be easy to overinterpret

A car dash cam with a 4K camera won’t produce perfect footage in every situation. Image quality also depends on lighting, positioning, storage and the viewing angle. According to the ESSGOO product descriptions, the cameras have a wide 140-degree viewing angle. That’s a specification you can check, but it doesn’t guarantee that every detail will be recognisable in every traffic situation.

The same applies to car wax. According to the carnauba wax product description, the protective coating could last for up to six months. In practice, how long it lasts depends on washing, weather, use and how well the paintwork is prepared.

3. Safety accessories can be used incorrectly

A car blind spot mirror is a helpful aid, not a replacement for your regular wing mirrors or looking over your shoulder. Its curved shape can distort your sense of distance. A car emergency hammer also has limitations: according to the product information, it’s designed for toughened side windows, not laminated windscreens, rear windows or panoramic roofs.

Important specifications to check

For infotainment and a dash cam

When choosing a CarPlay screen, check:

  • Smartphone compatibility: check which iOS and Android versions are required.
  • Power supply: many portable models use a 12V to 24V connection.
  • Storage: loop recording overwrites older footage. A supplied 64GB TF card is handy, but check the maximum supported capacity, too.
  • Audio connections: Bluetooth, AUX, an FM transmitter and a built-in speaker offer different options.
  • Fitting: the screen must not obstruct your view of the road. A sturdy mount and tidy cable routing are important.

A reversing camera can help with parking, but always check your mirrors and the area immediately around the car, too.

For visibility and glass cleaning

When choosing a car window wiper or squeegee, material, dimensions and instructions for use are especially important. Rinse away sand and dirt before using a silicone or rubber wiper. Wiping dry can cause scratches. A soft wiper is suitable for smooth glass, mirrors and certain smooth surfaces, but not for rough or hot materials.

A telescopic wing mirror wiper extending up to 98 cm is useful if you want to reach your wing mirrors from the driver’s seat. After use, check that the rubber is clean and store the tool somewhere dry.

For cleaning and paintwork care

If you’re planning to use car wash and wax or other car care products yourself, clean the surface first. Dust, sand and metal particles can cause scratches while you polish. Only use products intended for paintwork, and follow the recommended drying and buffing times.

For an upholstery cleaner or spot cleaner, consider its capacity, hose or cable length, noise level and accessories. A larger water tank is useful for cleaning several seats or floor mats, but it also makes the appliance heavier.

Frequently asked questions about car accessories

Which car accessories are useful for everyday use?

A phone or CarPlay screen, a compact car window squeegee, a car blind spot mirror and an emergency hammer are practical choices for many drivers. Choose according to your car, driving habits and storage space. For electronic products, always check the power supply, smartphone compatibility and fitting.

How do I care for a car window wiper or silicone wiper?

Rinse the window first if there’s sand or mud on it. Only use the wiper on a wet, smooth surface, and don’t apply excessive pressure. Rinse the blade with clean water after use, and store it away from direct sunlight and high temperatures.

How much does it cost to use car care products?

The cost depends on how much you use and how often you use it. A tin of wax or upholstery cleaner will last longer if you wash the car thoroughly first and use the product as directed. With electrical appliances, you should also consider power consumption, accessories and the cost of replacing filters or parts.
